Description

2-Hydroxy-3-Sulfanylpropanoic Acid is a versatile sulfur-containing organic acid with significant utility in advanced chemical synthesis. Its unique bifunctional structure, featuring both hydroxyl and sulfanyl (thiol) groups, makes it a valuable building block for creating complex molecules and functional materials. This compound is essential for researchers and manufacturers in the pharmaceutical, cosmetic, and specialty chemical industries seeking to develop novel compounds with specific biological or material properties.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring thiol or disulfide linkages for bioactivity.
• Cosmetic Ingredient: Used in the formulation of advanced skincare and haircare products, where it can act as an antioxidant or a precursor for compounds that promote skin health and repair.
• Biochemical Research: Employed as a reagent in peptide synthesis and protein modification studies, leveraging its thiol group for selective conjugation and cross-linking reactions.
• Polymer & Material Science: Functions as a monomer or cross-linking agent in the production of specialty polymers, coatings, and adhesives with enhanced properties.
• Chelating Agent: Utilized in formulations requiring metal ion chelation due to its hydroxyl and thiol functional groups.
• Flavor & Fragrance Synthesis: Acts as an intermediate in the creation of complex sulfur-containing flavor and aroma compounds.

Quality Control

Our 2-Hydroxy-3-Sulfanylpropanoic Acid is produced under a strict quality management system to ensure batch-to-batch consistency and high purity. We offer various grades, including technical and high-purity standards, to meet diverse application needs. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are provided with every shipment. Our quality protocols are designed to support compliance with cGMP, ISO, and REACH requirements for global supply.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its property of being easily oxidized, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from strong oxidizing agents, strong acids, and strong bases.
